* Data representation descriptor (drep)
*
* Note that the form of a drep "on the wire" is not captured by the
* the "ndr_format_t" data type. The actual structure -- a "packed drep"
* -- is a vector of four bytes:
*
* | MSB LSB |

* +---------+---------+
* | int rep | chr rep |

*
* The following macros manipulate data representation descriptors.
* "NDR_COPY_DREP" copies one packed drep into another. "NDR_UNPACK_DREP"
* copies from a packed drep into a variable of the type "ndr_format_t".
